Lewis Carl Davidson Hamilton (born 7 January 1985) is a British racing driver who races in Formula One for Mercedes-AMG Petronas Motorsport. A five-time Formula One World Champion, he is often considered the best driver of his generation and widely regarded as one of the greatest drivers in the history of the sport. He won his first World Championship title with McLaren in 2008, then moved to Mercedes where he won back-to-back titles in 2014 and 2015 before winning back-to-back titles again in 2017 and 2018. The most successful British driver in the history of the sport, Hamilton has more World Championship titles (5) and more race victories (81) than any other British driver in Formula One. He also holds records for the all-time most career points (3,268), the most wins at different circuits (26), the all-time most pole positions (87) and the most grand slams in a season (3).
Born and raised in Stevenage, Hertfordshire, Hamilton's interest in racing started when his father bought him a radio-controlled car when he was six. He was signed to McLaren's young driver support programme in 1998, after he approached McLaren team principal Ron Dennis at an awards ceremony three years earlier and said "one day I want to be racing your cars". After winning the British Formula Renault, Formula 3 Euro Series, and GP2 championships on his way up the racing career ladder, he made his Formula One debut twelve years after his initial encounter with Dennis, driving for McLaren in 2007. Coming from a mixed background, with a black father and white mother, Hamilton is the first and only black driver to race in Formula One.
In his first season in Formula One, Hamilton set numerous records as he finished runner-up in the 2007 season to Kimi Räikkönen by just one point, including those for the most consecutive podium finishes from debut (9), the joint most wins in a debut season (4) and the most points in a debut season (109). The following season, he won his first title in dramatic fashion; on the last corner of the last lap in the last race of the season, becoming the then-youngest Formula One World Champion in history. After four more years with McLaren without finishing higher than fourth in the drivers' standings, Hamilton signed with Mercedes in 2013, reuniting with his childhood karting teammate, Nico Rosberg. In his first season, he finished 4th once again, the third time in five years.
Changes to regulations mandating the use of turbo-hybrid engines contributed to the start of a highly successful era for Hamilton and Mercedes, during which he has won a further four World Championship titles. Hamilton won consecutive titles in 2014 and 2015 during an intense and sometimes volatile rivalry with teammate Nico Rosberg, to match his hero Ayrton Senna's three World Championships. Following Rosberg's retirement, Ferrari's Sebastian Vettel became Hamilton's closest rival as the pair engaged in two intense championship battles, but Hamilton prevailed to claim consecutive titles for the second time in his career in 2017 and 2018, joining Juan Manuel Fangio and Michael Schumacher as drivers with five or more World Championship titles.
